Two masses of 14,5 kg and 17,91 kg respectively are firmly attached to a rotating faceplate on a lathe. the 14,5 kg mass is attached at a radius of 91 mm and 17,91 kg mass at a radius of 101 mm from the centre o. the eccentricities of the 14,5 kg mass and the 17,91 kg mass are at an angle of 120° to one another. determine the distance where a 15 kg mass must be placed to balance the system

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
